Information
It is essential for security personnel to know what is being done, what was attempted, where it was done, when it was done, and by whom it was done in order to compile an accurate risk assessment. Associating event types with detected events in the application and audit logs provides a means of investigating an attack; recognizing resource utilization or capacity thresholds; or identifying an improperly configured network device. Without this capability, it would be difficult to establish, correlate, and investigate the events leading up to an outage or attack.
Solution
Enable logging on the switch with sufficient detail to establish what type of event occurred.
To configure logging to a remote syslog server at the informational level, enter:
switch#config
switch(config)#logging host [ip address]
switch(config)#logging trap informational
